Re: focing users to login from the root
It starts, as most stories do, at the beginning.
Once upon a time, there was a function called wp_loginout(). It happily printed links to allow the user to log in or out, depending on whether the user was already logged in or not. It was so popular, other kids like the Default WPMU theme used it, and lived in a small cottage in the town of /wp-includes/general-template.php.
wp_loginout()’s most popular attribute, however, wasn’t its fantastic collection of designer shoes, nor golden rings, but its filter called loginout. This let its very closest friends have access to its link string.
One controversy that springs to mind, after skipping over a few minor details, happened in /wp-includes/link-template.php street, in site_url‘s house. Its cousin, get_option(‘siteurl’), got around a bit – I’m sure you can imagine, but when it was in one place it was saying one thing, and when it was in another, another thing; it had its own confusingly-named filter site_url, but perhaps this filter was less suited than the other. Needless to say, Mrs. get_option(‘siteurl’) eventually found out about this behaviour and took things into her own hand – she got out some string function, and chopped it up small – ouch!
I think I might still have the original newspaper article here, let me go look. I think it had a picture.
